This invention frelates to a dye jig forruse in connection with thefinishing of textile material Or'for like use, and has for one of itsobjects to provide a construction with an independent simplified drivefor each tank.

Another object of this invention is the provision of a Construction inwhich an electric motor may be utilized for independently driving eachjig.

I Another object of this'invention is the provision of a dyejigconstruction in which the.

jigs will each have an independent drive mounted Completely upon eachjig to cause each jig to be morepaccessible and permit the operator tofreely walk Y completely around each tank if desired.V

A further object of this invention is the provision ofY a constructionwhich will be Vquiet in operation and one which will have a minimumvibrationA and wear upon the parts. v

A still further object Vof this invention is the provision of a controlmeans which may.

be operated from either side of each tank and in which the control ofthe different feed rolls will be simultaneous.

' With these'and other objects in view, the invention consists' ofcertain novel features ofc'on'struction, as will bemore fully described,and particularly pointed out in the appended claims. Y Y Y Y In theaccompanyingdrawings:`

Y l j Fig. 5 is a perspective skeletonviewof the control means for operating the clutches for the feed rolls'.V i i f In the operation of dye jigs it has been usual to connect thefeed rolls Aofa series ofdye jig tanks to a'lcommon operating driveshaft extending longitudinally along a length of tanks by such means asbevel gears or the like for operating the dierent feed rolls and tocontrol the operation of each feed roll by a suitable clutch mechanism.vlIt has been customary to use considerable additional gearing mechanismwhen the power is furnished by an electric motor as the motor must itravel at a relatively high rate of speed, compared to the .rotationdesired on the feed rolls ofthe tank, necessitating a train of severalreduction gears of different sizes intermeshing to obtain the desiredreduction before the shaft is rotated, and in order to substantiallyreduce this usual gearingl and provide an independent operation of eachtank, I have kutilized an electric motor for directly operating separatedrive shafts for each tank j and driving each ofthe feed rolls from thedrive shaft by worm .and worm gears, thus providing asingle'pair'ofquiet running gears and an independent drive foreach unit; and thefollowing is a detailed description of the present embodimentv of thisinventi on illustrating the preferred means by which these advantageousresults may be accomplished. A j 1 With reference tothe drawings, 10desig-V nates the tank which vis supported by suitable frame workllhhavinnfl feet 12 to rest upon the floor or other suitable support.Within each tank there is a speciallyk constructed metal frame whichsupports guide rolls 13, 14, y,15 and 16 over which the traveling web 17of textile fabric or the like is conducted from a package 18 rotatingabout an aXis 19 to the package 20 rotated about the aXis 21 'orvice-versa through the bath contained in the tank 10.

Y This above kdescribed portion of the devic-epis somewhat the usualconstruction, and the invention relates more particularly to the drivingof the feed rolls 22 and 23 which are mounted upon suitable shafts 24and 25.

shaft 24 and 25 intermeshing with worms on the drive shaft 28.

An electric motor 3l has its axis of rotation axially aligned with thedrive shaft 28 and is coupled thereto by a suitable coupling 32for-rotating the drive shaft 28. rIhe coupling 33 is alsointerpositioned in the :drive shaft 28 for convenience of assembly.

The worm and worm gears are enclosed in a housing 34 and 35 Vwhich alsoprovides bearings 36 and 37 at each end thereof for the better supportof the drive shaft 28. v The housing 34 is liquid tight to contain alubricant for the gears to assist the quiet operation of the device andprevent Wear on the operating parts and also by having the lubricantentirely enclosed in this manner it cannot be spattered into thetreating tank to soil the goods. Y

Each of the clutches 27 are provided with a collar 38 grooved as at 39,in which a ring 40 is located. Pins4l and 42 extend from diametricallyopposite sides of the ring, and

\ in order to shift the clutch member 43 to and from engagement with itscompanionmember 44, I have mounted a bracket 45 on the frame 46 of thedevice which supports an upwardly extending pivot pin 47 and lon thispin I have mounted the hub member 48 from which there extends bifurcatedarms 49, slotted as at 50 to engage the pins 41 and 42 of the ring `40,so that movement of the lever 51 will control the action of each of therolls by moving'the clutch into or out of operative position.

The members 48 are also provided with arms 52 extending laterally fromthe hubs and are connected by means of a link-53 soy that when either ofthe levers 51 which eX- Oi i tend from opposite sides of the machine aremoved by the operator, the opposite clutch and lever is also moved, thusboth clutches may be operated in unison from either side e of theapparatus to accomplish direction of rotation desired.'

lIn operation when the roll 22 is functioning to lfeed the web bydrawing it from the package 20, the clutch 27 of the shaft 24 is inengagement to cause a drive of the package 18 and the clutch on theshaft 25 connected therewith to freelyV rotate. When it is desired todraw the cloth from package 18 to wind `it upon package 2OA the roll 23is driven and the clutch on roll 22 will be positionel to permit thesame freely to rotate, thus it will be observed that a shifting of alever 51 at one side of the machine to throw the clutch into operativeposition will simultaneously cause a movement ofthe clutch on the otherside of the machine to throw the clutch. outY of engagement, while thearrangement is Such that there is an intermediate position in which bothclutches are in neutral.

By the construction which I have above described an independent drive isprovided for each tank, thus eliminating the common connecting shaft fora series of tanks and permitting the operator to move freely andcompletely about each tank for inspection and manipulation of the workas desired. Also by this construction I provide a thirty to one, or anydesired reduction, in the speed of rotation by the spiral gears,enabling the feed roll to be driven directly from the electric motorshaft without the necessity for providing a train of intermeshing spurgears, .and also by enclosing the gears I am enabled to run them inlubricant and provide a more quiet and eicient drive and one in whichthe dye bath and work are free from soil. Also as each ljig isindependent a constant or variable speed motor may be provided to rundifferent tanks at different speeds, thus allowing fargreaterflexibility of action and manipulation of the work.

In some instances the web is reeled -directly on the roll 22 or 23 andin such instances the use of the variable speed motor enables me to drawthe web through the heating bath at a substantially constant speed ifdesired `therebyzeliminating a variation in .speed due tothevaryingdiameter of the reeled package. Also by the use of a variable speedmotor I am enabled to operate the tank at different speeds for differentclasses of work, thus permitting .the work to be passed through the tankslowly in some cases or faster for other classes of work.

The foregoing description is directed solely towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being defined and limited only by theterms of the appended claims.

I claim:
